To allwhom z'tmay'co'ncem:

Be it 'known that I, JOHN A. EMERSON, a citizen of the United States, and resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Devices for Removing Glinkers from Furnaces;jand I do herebydeclare that the following description of my invention, taken in connection with the accompanying sheet of drawings, forms a' full, clear, and exact specification, which will enable others skilled in the art to which the said invention appertains to make and use the same.

This invention has general reference to clamping devices, and it consists, essentially, in the novel and peculiar combina' tion of parts, and details of construction, as hereinafter, first fully set forth and described, and then pointed out in the claim.

The object of this invention is the production of an eflicient, serviceable, convenient, and comparatively inexpensive device for removing clinkers from furnaces and the like.

It is a well-recognized fact that there is considerabledifliculty experienced in removing clinkers from furnaces in operation, partly due to the heat emitted when the fire doors are open, and the difliculty in catching the clinkers for removal, especially in furnaces where the grate bars are below the fire door, and cannot be easily reached by the means in common use.

To overcome these difiiculties, I provide a device which can be readily handled and which combines a poker or slice bar with means for grasping clinkers and hold them so that they may be effectively removed from the furnace while the fire is burning.

In the drawings, which illustrate the preferred embodiment of my invention, and form a part of this specification,

Figure 1 is an elevation of my improved slice bar and fire tongs combined. Fig. 2 is a similar View of the device as it appears after having been rotated through an angle of 90 degrees from that shown in Fig. 1.

Like parts are indicated by the same characters and symbols of reference in both figures.

A, in the drawings designates an iron rod of proper length and diameter, which rod is, preferably, tubular in form and which may be, for general purposes, a commercial iron pipe of inch diameter, which meas- Specification of Letters Patent;

ures externally approximately 1 inch in ends, as at 12, and terminates in a blunt point 13 or a separate flat bar'may be welded connected ahand'lever 18, of approximately" V-shape, by its arm 19, which is forked at this point, and flattened as at 20. To this flattened member thereis hitched a rod 21, which extends downwardly and has its lower end connected to the arm 22 of the lever B, in a hole 25 therein.

In the tubular rod A there are spaced apart openings 23, 24, the.pull rod21 entering the tube through the'opening 23, and passing out of the same at 24,,so that this rod, which may be a comparatively light wire, (it being subjected to tension only) will not be disturbed when the device is, be-; ing used. 7

At a point 26, opposite the opening 25 in the arm 2-2, there is attached a wire rod 27 end of this tube, if desired.

18 is properly n1anip-' and terminating in. y

the spike 12 and grasp and hold any article that may become engaged by these elements. It will now be noted that this instrument is especially well adapted for use in con-V nection with furnaces, particularly when'in operation, inasmuch as the spike 12 may perform the function of a slice bar to lift the clinkers, slag, etc., from the grate and grasp them between the point 13 and 16 of the device, andthen lift them out of the furnace.

The simplicity of this device is at onceapparent; and since it can be manufactured and sold at a very reasonable price, it will fill a long-desired want for an instrument of the nature described.

Having thus fully described this invention, I claim as new, and desire to secure to myself by "Letters Patent of the United States- An instrument for removing clinkers from furnaces and the like, consisting, in combination, of a tubular rod, said rod having at one of its extremities a flattened bar, said.

bar terminating in a blunt point, a curved lever pivotally connected to said flattened bar, said curved lever having one of its terminals inwardly turned, approximately at right angles, the right angled portion being formed to a blunt edge, a hand lever pivotally connected to the other end of said tubular rod, a wire rod connected with one of its ends to said curved lever at the other end of its terminals, the other end of said wire rod being connected to said hand lever,

there being in one side of said tubular rod an opening through which said wire rod passes into, and at the other side an opening through which said wire rod passes out of said tubular rod, and means for keeping the inwardly turned end of said curved lever normally at a distance from the pointed end of said flattened bar, said means being connected to said curved lever at a point opposite that where the wire rod is connected thereto.

In testimony that I claim the foregoing as my invention, I have hereunto set my hand.

JOHN A. EMERSON.
